Modified design question

[Danno-TNT]

ok, next question in the design is how do I attach the roof to the sides?

I want to maximize my interior space, so I was wondering about spars or horizontal bracing for the roof. I've decided on 1/2 floor and 1/4 sides and roof.

Since it's only spanning 40",
1. do I need horizontal bracing?
2. should the roof rest on top of the sides, or between the sides?
3. could I get by with 1x2s for the curve of the side and screw the top into that? if so, can I get 1x2s to bed easily enough?
4. Will 1/4 plywood bend the tight radius you see in the plan above?

I've looked at some other builds, but just am temporarily struggling with this. anyone have any advice?

I am buidling #2 on what used to be a 40 x 48 trialer, I stretched the frame out to 80 inchs.

I will also be stretching the tongue an additional 2 foot.
